If you want lightweight, foldable wired headphones for small ears, choose ELECDER i37; if you need wireless in-ear earbuds with active noise cancellation, choose Moondrop Space Travel 2+Magnetic. The i37 is the simpler fit for school bags and devices with a headphone jack, while Moondrop adds Bluetooth, selectable ear tips, and a charging case.
• ELECDER i37 strength: A foldable, 5.6-ounce on-ear design with a 3.5 mm plug; trade-off: it is wired and has no wireless connection.
• Moondrop Space Travel 2+Magnetic strength: Bluetooth 6.0, active noise cancellation, and a supplied magnetic protective case; trade-off: it is an in-ear design that needs charging.
• The i37 suits children, teens, and people with smaller heads or ears who want a straightforward wired option.
• Moondrop suits listeners who want wireless playback, ANC, and a choice of S, M, or L ear tips.
• For a small-ears purchase, decide first whether a lightweight on-ear fit or a seal inside the ear is more appealing.
The ELECDER i37 is a compact on-ear headphone with a wired 3.5 mm connection. Its foldable construction is useful when headphones need to move between a desk, school bag, or suitcase. At 5.6 ounces, it is relatively light on paper, and its design is described as suitable for children as well as short, small, or petite adults. Those details make it a practical candidate for small ears, though an on-ear fit is not the same as an in-ear ear-tip fit.
The L-shaped plug is designed for devices with a 3.5 mm audio jack. That includes a range of listed devices such as laptops, PCs, tablets, smartphones, DVD players, and Kindles. A wired connection avoids managing a Bluetooth pairing or recharging the headphones, but it also means the listening device needs a compatible jack. The i37 has a dynamic driver, a stated 20 Hz–20,000 Hz frequency range, sound isolation, and a remote media control. Its specifications describe the hardware, but they do not establish how it will sound to every listener.
I would consider the i37 for schoolwork, travel, or everyday listening when a compatible device is close at hand and a foldable on-ear style is preferred. Its straightforward setup may also suit a child’s device without adding wireless pairing steps. Skip it if you need Bluetooth, active noise cancellation, or a cable-free setup. The product details do not specify a water-resistance rating, so I would not choose it on the assumption that it is built for sweat or water exposure.

Moondrop Space Travel 2+Magnetic is the more feature-heavy choice for someone seeking wireless in-ear earbuds. It uses Bluetooth 6.0, lists a 10-meter range in an open environment, and supports SBC and AAC codecs. The in-ear design comes with S, M, and L ear tips, giving the wearer three supplied sizes to try. That makes it worth considering for small ears, but the listed tip sizes alone cannot guarantee that a particular earbud will feel secure or comfortable.
Active noise cancellation is a key difference from the i37. Moondrop describes a feedforward ANC approach, while its environmental noise-cancellation system is intended to help voice clarity. These features may appeal to people who listen in busy surroundings or make calls, but the product information does not provide a water-resistance rating or quantify the amount of noise reduced. It also includes a low-latency game mode, with a stated signal delay as low as 55 ms, and a one-button EQ setting through the MOONDROP app.
The listed battery life is about seven hours for the earbuds using AAC, with about 24 hours stated for the charging case. Those figures give a useful reference for planning listening sessions, but they mean charging remains part of ownership. The package includes a magnetic protective case made of transparent PC, along with a charging cable and ear tips. Skip Moondrop if you prefer an on-ear fit, want to avoid charging, or need a stated waterproof rating.
• Best for a wired setup → ELECDER i37. Its 3.5 mm plug suits devices that have a compatible headphone jack.
• Best for Bluetooth listening → Moondrop Space Travel 2+Magnetic. It uses Bluetooth 6.0 and lists a 10-meter open-environment range.
• Best for avoiding battery management → ELECDER i37. It connects by cable and does not rely on a wireless battery.
• Best for active noise cancellation → Moondrop Space Travel 2+Magnetic. ANC is a stated feature; the i37 lists sound isolation instead.
• Best for choosing among included ear-tip sizes → Moondrop Space Travel 2+Magnetic. S, M, and L tips are included, although fit still depends on the individual wearer.
• Best for folding into a school bag or suitcase → ELECDER i37. Its foldable design is specifically suited to compact storage and carrying.
• Best for a stated game-mode delay → Moondrop Space Travel 2+Magnetic. Its game mode specifies transmission delay as low as 55 ms.
• Best for a small-ears buyer who wants on-ear headphones → ELECDER i37. Choose it for the on-ear format; choose Moondrop if an in-ear fit and interchangeable tip sizes are the priority.
Buying Considerations
For small ears, “on-ear” and “in-ear” describe different ways a product fits, not two versions of the same fit. The i37 sits on the ears, while Moondrop uses ear tips inserted into the ears. If pressure from an in-ear seal is a concern, the i37’s format may be more appealing. If having multiple tip sizes to try matters more, Moondrop provides S, M, and L options. Neither set of specifications can predict a comfortable fit for every person.
Use cases involving exercise or wet weather need particular care. The supplied details do not give an IP rating for either product. So neither should be treated as a confirmed sweat-resistant or waterproof choice based on this comparison. If you are searching for the best sweat resistant earbuds for small ears, look for a clearly stated water-resistance rating before deciding. Likewise, the phrase best open ear headphones for small ears does not describe either product precisely: the i37 is on-ear, and Moondrop is in-ear. Neither is identified as an open-ear design.
Finally, avoid reading more into the audio specifications than they establish. The i37 lists a 20 Hz–20,000 Hz frequency range and a dynamic driver. Moondrop lists a 13 mm dynamic driver, ANC, and one-button EQ settings. Those are useful differences in design and features, but they do not supply a direct listening comparison or prove that one will sound better to every buyer. If you are considering IPX7 waterproof on ear headphones for small ears, neither product’s provided details state IPX7 protection. Check the current product information for a confirmed rating rather than inferring it from the style or intended use.
In my opinion, I would choose the ELECDER i37 for a child or petite listener who wants a foldable on-ear headphone and has devices with a 3.5 mm jack. For small ears, its on-ear format is a straightforward alternative to earbuds, with no wireless charging routine. I would pick Moondrop instead if Bluetooth, ANC, and several ear-tip sizes matter more. My small-ears recommendation is the i37 for simple wired listening; I would not call either one a waterproof or sweat-rated pick from the listed information.
FAQ
No wireless connection is listed for the i37. It connects through a 3.5 mm jack, so the device needs a compatible port for a direct connection.
The listed earbud battery life is about seven hours using AAC. The charging case is listed for about 24 hours; actual use may vary, and charging is part of using a wireless set.
Do not assume they are sweat-resistant or waterproof, including IPX7, without a specific rating confirmed for the product.
